Ergotamine is a medication primarily used to treat migraine headaches. It belongs to a class of drugs known as ergot alkaloids and works by constricting blood vessels around the brain. Ergotamine helps alleviate headache pain and other symptoms associated with migraines, such as nausea, vomiting, and sensitivity to light and sound. However, it is not used for the prevention of migraines and should be taken only during a migraine attack. Due to its ability to narrow blood vessels, ergotamine can cause serious side effects, particularly if overused, and is contraindicated in patients with certain cardiovascular conditions. It’s also known to interact with other medications, so careful monitoring is essential.
